7月中旬,受西太平洋副热带高压带加强并向北抬升的影响,我国北方地区出现了2016年入汛以来首次范围广、强度大的降雨过程,原本就不平静的汛情变得更加危急。7月19日凌晨,在孕育悠久殷商文化的古都安阳,一场特大暴雨不期而至,多项雨量数据突破历史最高纪录,安阳林州市东岗雨量站的24小时雨量达到697mm之多。随后,主雨区继续东移北抬,将这一轮强降雨又带到了京津冀。从19日到21日,首都北京大雨瓢泼,整个降雨过程长达近55小时,降雨总量更是超过了4年前造成惨重损失的“7·21”特大暴雨。
In mid-July, due to the intensification of the western Pacific subtropical high belt and its uplift to the north, the first extensive and intensive rainfall since the flood season in 2016 appeared in the northern part of our country. The originally not calm flood was even more critical. In the early morning of July 19, in Anyang, the ancient capital that gave birth to the culture of Shang merchants, a number of rainfalls unexpectedly exceeded the record high in many rainfall data. The rainfall in the 24-hour rainfall of Donggang rainfall station in Linzhou City, Anyang reached 697mm . Subsequently, the main rain area continued its eastward move to the north, bringing this round of heavy rainfall to Beijing, Tianjin and Hebei. From the 19th to the 21st, the heavy rain poured into Beijing’s capital Beijing. The entire rainfall lasted for nearly 55 hours. The total amount of rainfall exceeded the heavy rainfall of “7.21” that caused heavy losses four years ago.
